What makes System 0 different?
- Domain-agnostic: It works on code, contracts, configs, docs. If it is in a directory, System 0 can analyze it.
- Self-improving: Each analysis pass generates new angles to examine. The system gets smarter over time.
- Safety-first: Four execution modes let you control exactly how much autonomy the system has. Budget limits, maturity gates, and isolated worktrees prevent accidental damage.
- Transparent: Every finding, decision, and action recorded in an immutable ledger. Complete audit trail.
- Runs unattended: Install as a daemon and let it work 24/7 in the background.
